With the rapid development of science and technology and industrial economy in recent years, the demand for aluminum alloy welded structural components has been increasing, leading to in-depth research on the weldability of aluminum alloys. The widespread application of aluminum alloys has promoted the development of aluminum alloy welding technology, and the development of welding technology has in turn expanded the application fields of aluminum alloys. Therefore, aluminum alloy welding technology is becoming one of the research hotspots.

[0003] Chinese Patent CN213018841U discloses a high-strength, high-toughness aluminum alloy profile, including an inner profile and an outer profile. The inner profile is cuboid in shape, and the outer profile includes two wavy first side plates and two rectangular second side plates. The two first side plates are arranged opposite each other, and the two second side plates are arranged opposite each other. The first side plates and the second side plates are fixedly connected. Support rods are provided between the protrusions of the first side plates and the inner profile, and several spring rods are provided between the second side plates and the inner profile. However, the aluminum alloy profile in the above patent has a relatively simple structure, insufficient strength, poor toughness, and is prone to deformation. Moreover, the connection is relatively inconvenient. Therefore, we propose a high-strength, high-toughness aluminum alloy profile to solve the above problems. Utility Model Content

[0007] In a further embodiment, the aluminum alloy body includes a through groove, a fixing plate is fixedly connected inside the through groove, and connecting plates arranged at equal intervals are fixedly connected to the outer surface of the fixing plate.

[0008] In a further embodiment, each of the connecting plates has a symmetrical positioning strip fixedly connected to its outer surface, and the side of each set of positioning strips that is close to each other is connected to the outer surface of the fixed plate.

[0009] In a further embodiment, the inner wall of the through groove is fitted with compression springs arranged at equal intervals, and the end of each compression spring that is close to each other is connected to the outer surface of the fixing plate.

[0011] In a further embodiment, the aluminum alloy body has two sets of reinforcing ribs inside, and the aluminum alloy body has equidistantly arranged tough plates inside.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device reinforces the aluminum alloy body through reinforcing grooves, increasing its compressive strength. Reinforcing holes increase its bearing capacity. The combination of reinforcing ribs and toughening plates enhances its toughness, preventing deformation. Fixing and connecting plates reinforce the interior of the aluminum alloy body. Compression springs and positioning strips further increase its compressive strength. The fixing base, slots, and positioning angle plates position the aluminum alloy body, facilitating connection and installation. Attached Figure Description

[0022] Example 1:

[0023] Please see Figure 1-4 In this utility model, a high-strength and high-toughness aluminum alloy profile includes an aluminum alloy body 1. The surface of the aluminum alloy body 1 is provided with a 10-20μm ceramic layer generated by micro-arc oxidation, with a hardness of HV1500. The aluminum alloy body 1 is provided with a reinforcing mechanism 2 inside, a connecting mechanism 3 on the outer surface of the aluminum alloy body 1, and reinforcing grooves 4 arranged at equal intervals on the upper surface of the aluminum alloy body 1. Two sets of reinforcing holes 6 are provided on the front side of the aluminum alloy body 1. The reinforcing holes 6 are honeycomb-shaped weight-reducing cavities with micro-arc oxidation coating on the cavity walls. The aluminum alloy body 1 is provided with two sets of reinforcing ribs 5 inside, and toughness plates 7 arranged at equal intervals inside the aluminum alloy body 1.

[0024] Specifically, the aluminum alloy body 1 can be reinforced by the reinforcing groove 4, increasing the compressive strength of the aluminum alloy body 1. The compressive strength of the aluminum alloy body 1 can be increased by the reinforcing hole 6. The toughness of the aluminum alloy body 1 can be increased by the combination of the reinforcing rib 5 and the tough plate 7, thus preventing the aluminum alloy body 1 from deforming.

[0025] Example 2:

[0026] This is an improvement on the previous embodiment.

[0027] Specifically, the aluminum alloy body 1 includes a through groove 201, a fixing plate 202 is fixedly connected inside the through groove 201, and connecting plates 203 arranged at equal intervals are fixedly connected to the outer surface of the fixing plate 202. Each connecting plate 203 has a symmetrical positioning strip 205 fixedly connected to its outer surface. The side of each group of positioning strips 205 that is close to each other is connected to the outer surface of the fixing plate 202. Compression springs 204 arranged at equal intervals are installed on the inner wall of the through groove 201. The end of each compression spring 204 that is close to each other is connected to the outer surface of the fixing plate 202. Through the cooperation of the fixing plate 202 and the connecting plate 203, the interior of the aluminum alloy body 1 can be reinforced. The compression strength of the aluminum alloy body 1 is increased by the cooperation of the compression springs 204 and the positioning strips 205.

[0028] Specifically, the connecting mechanism 3 includes two fixed seats 301. Each of the two fixed seats 301 has a slot 302 on one side away from each other. Two sets of positioning angle plates 303 are installed on the outer surface of the aluminum alloy body 1. Through the cooperation of the fixed seats 301, slots 302 and positioning angle plates 303, the aluminum alloy body 1 can be positioned, which facilitates the connection and installation of the aluminum alloy body 1.

[0029] The working principle of this utility model is as follows:

[0030] In use, the aluminum alloy body 1 is formed through melting and casting, homogenization treatment, and hot extrusion with an extrusion ratio ≥30:1. It then undergoes a three-stage aging treatment: 120℃×8h + 180℃×4h, resulting in a tensile strength ≥420MPa, a yield strength ≥380MPa, an elongation ≥12%, and an impact toughness of 80J / cm². 2 The aluminum alloy body 1 can be reinforced by the reinforcing groove 4, increasing its compressive strength. The reinforcing hole 6 can increase its bearing strength. The combination of the reinforcing rib 5 and the toughness plate 7 can increase the toughness of the aluminum alloy body 1 and prevent it from deforming. The combination of the fixing seat 301, the slot 302 and the positioning angle plate 303 can position the aluminum alloy body 1, making it convenient to connect and install the aluminum alloy body 1.
